摘要
介绍了一种基于光电传感器的风机转速测量系统的软硬件设计。该测量系统采用光电传感器实施转速测量,它有红外发射和红外接受装置组成,通过把光强度的变化转换成脉冲信号的变化来实现转速计数测量。硬件系统包括脉冲信号产生、单片机信号处理系统和显示模块,软件程序采用C语言编程。测试结果表明该仪器具有实时测量、精度高、稳定性好的优点。
An instrument design and test principle for measuring fan rotational speed based on photoelectric sensor was reported in this paper. The hardware and software system design was mainly presented. The photoelectric sensor is formed by an infrared emission control and a receiving diode. The optical pulse for measuring rotational speed of the motor was produced by blocking up the optical path intermittently.The hardware included pulse signal generation, microcontroller signal processing system and display module The software for monitoring was designed by C language. The test shows that the measuring system can guarantee a real-time detection and high precision.
